In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GT 720M are very slightly better than the Nvidia GeForce GT 630M.

The GeForce GT 630M has a 35 MHz higher core clock speed and the same number of Texture Mapping Units as the GeForce GT 720M. This results in the GeForce GT 630M providing 0.6 GTexel/s better texturing performance. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The GeForce GT 630M has a 35 MHz higher core clock speed than the GeForce GT 720M, but the GeForce GT 720M has 4 more Render Output Units than the GeForce GT 630M. As a result, the GeForce GT 720M exhibits a 2.4 GPixel/s better Pixel Fill Rate than the GeForce GT 630M. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The GeForce GT 720M was released over a year more recently than the GeForce GT 630M, and so the GeForce GT 720M is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GeForce GT 630M.

The GeForce GT 720M and the GeForce GT 630M have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The GeForce GT 630M has 14.4 GB/sec greater memory bandwidth than the GeForce GT 720M, which means that the memory performance of the GeForce GT 630M is slightly better than the GeForce GT 720M.

Both the GeForce GT 720M and the GeForce GT 630M have 96 Shader Processing Units. While the two GPUs have the same number of SPUs, the actual performance delivered by the GeForce GT 720M is 180 and by the GeForce GT 630M is 127. Knowing that the shader performance of the GeForce GT 720M is superior, it is not necessary to examine the GPUs' respective Texture and Pixel Fill Rates.

The GeForce GT 720M transistor size technology is 12 nm (nanometers) smaller than the GeForce GT 630M. This means that the GeForce GT 720M is expected to run slightly cooler and achieve higher clock frequencies than the GeForce GT 630M. While they exhibit similar graphical performance, the GeForce GT 720M should consume less power than the GeForce GT 630M.

The GeForce GT 720M requires 33 Watts to run and the GeForce GT 630M requires 33 Watts. The two GPUs require the same amount of wattage to run. As such, there is no need to worry about which will more significantly affect your yearly electricity bills.

Mini Review

Overview
GeForce GT 720M is a entry-level Mobile Graphics Card based on the second revision of the Fermi Architecture.

Architecture
The Fermi Architecture is manufactured with a 40nm Technology and uses a technique known as Hot Clocking: The Shaders are clocked twice as fast as the Central Unit. While this leads to a reasonable performance boost, it causes enormous amounts of energy dissipation, leading, ultimately, to a significantly higher operating temperature.
Fermi is also the first GPU architecture with fully cached memory access which increases memory performance.

GPU
It equips a GPU Codenamed GF117-N14M-GE which has 2 Stream Multiprocessors activated and thus offers 96 Shader Processing Units, 16 TMUs and 8 ROPs. The Central Unit is initially clocked at 625MHz and may reach up to 938MHz, in Turbo Mode.
Additionally, GF117 is built using a 28nm technology.

Memory
The GPU accesses a 1GB frame buffer of DDR3, through a 64-bit memory interface. The size of the frame buffer is exaggerated and no way benefits the GPU. The Memory Clock Operates at 900MHz.

Features
DirectX 11.0 Support (11.0 Hardware Default) and support for Optimus, 3D Vision Surround, PhysX, Realtime Raytracing and other technologies

Power Consumption
With a rated board TDP of 33W, it is suited for average sized laptops.

Performance
GeForce GT 720M is essentially a fast GeForce GT 620M with the option for the Boost Clock which depends on the laptop's cooler.
Gaming benchmarks indicate its performance is slightly below the older GeForce GT 635M.

System Suggestions
We recommend a modest processor (Intel Core i3 Mobile) and 4GB of RAM for a system with GeForce GT 720M.
